comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولThe iron-H2O2-iodide cytotoxic system
A potent antimicrobial system is described which consists of ferrous sulfate (Fe2+), hydrogen peroxide (H2O2), and iodide in 0.02 M sodium acetate buffer pH 5.5. H2O2 could be replaced by the H2O2-generating system glucose + glucose oxidase. This system, unlike the myeloperoxidase-H2O2-halide system, was ineffective when iodide was replaced by bromide, chloride, or thyroxine, and was inhibited ...
متن کاملGold, Silver and Iron in Iron Oxy-hydroxide Precipitate Formed in Process of Acid Mine Drainage
Oxidation of sulfide-containing ores is the main cause of Acid Mine Drainage (AMD), which is an environmental problem associated with both the abandoned and active mines. Iron-bearing sulfide minerals can be oxidized and form mine waters with high sulfate content, low pH, high electrical conductivity, high redox potential, and high concentrations of iron, aluminum, and other heavy metals. In th...
متن کاملIron (FeSo4) bioavailability in obese subjects submitted to bariatric surgery.
BACKGROUND Iron bioavailability in obese subjects after the ingestion of a nutritional supplement was the aim of this work. METHODS Fourteen persons were studied before and after bariatric surgery after the ingestion of a nutritional formulation containing 25 mg iron, 25 g fiber and 800 mg calcium. RESULTS The following ferremia values (median and minimum--maximum) were obtained before and ...
